Craig Topper 01bba17819 Recommit r299321 '[X86] Add __extension__ to f16c macro intrinsics to suppress warnings about compound literals when compiled for with earlier language standards enabled.'
The bot didn't recover after the revert. So it looks like this wasn't the issue.

Ekaterina Romanova dffe45b3e6 [DOXYGEN] Improved doxygen comments for x86 intrinsics.
Improved doxygen comments for the following intrinsics headers:  __wmmintrin_pclmul.h, bmiintrin.h, emmintrin.h, f16cintrin.h, immintrin.h, mmintrin.h, pmmintrin.h, tmmintrin.h

Added \n commands to insert a line breaks where necessary, since one long line of documentation is nearly unreadable.
Formatted comments to fit into 80 chars.
In some cases added \a command in front of the parameter names to display them in italics.

Ekaterina Romanova 0c1c3bbc78 [DOXYGEN] Improved doxygen comments for x86 intrinsics headers.
Tagged instruction names with <c> INSTR_NAME </c> to display them in typewriter font.

In the past, \c command was used, unfortunately it applied to only one word. 
<c> .. </c> has the same meaning, but applies to all words in between the tags.

Ekaterina Romanova 1168fdc9df Doxygen comments for avxintrin.h.
Added doxygen comments to avxintrin.h's intrinsics. As of now, only around 50% of the intrinsics in this file are documented here. The patches for the other half will be sent out later.

Updated bmiintrin.h to fix an incorrect section name.
Updated f16cintrin.h to fix incorect parameter names.


The doxygen comments are automatically generated based on Sony's intrinsics document.

I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream.

Ekaterina Romanova a61946d551 This patch adds doxygen comments for all the intrinsincs in the header file f16cintrin.h. The doxygen comments are automatically generated based on Sony's intrinsics document.

Paul Robinson 941bc91518 Move _mm256_cvtps_ph and _mm256_cvtph_ps to immintrin.h.
This more closely matches their locations as described by Intel
documentation, and lets us remove a pair of redundant typedefs.

Eric Christopher 9fc7fb274e Update the intel intrinsic headers to use the target attribute support.
This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:

int __attribute__((__target__(("sse3")))) foo(int a) {
  _mm_mwait(0, 0);
  return 4;
}

This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.

Eric Christopher 4d185168e9 Use a define for per-file function attributes for the Intel intrinsic headers.
This is a precursor to changing them to use the new target attribute
code.

David Blaikie 3302f2bd46 PR14964: intrinsic headers using non-reserved identifiers
Several of the intrinsic headers were using plain non-reserved identifiers.
C++11 17.6.4.3.2 [global.names] p1 reservers names containing a double
begining with an underscore followed by an uppercase letter for any use.

I think I got them all, but open to being corrected. For the most part I
didn't bother updating function-like macro parameter names because I don't
believe they're subject to any such collission - though some function-like
macros already follow this convention (I didn't update them in part because
the churn was more significant as several function-like macros use the double
underscore prefixed version of the same name as a parameter in their
implementation)
